Expected Behavior

1. Press LShift to dismount a broom, getting off of it and proceeding on foot
2. Reticle being centered on an Enderman's head and torso angering it into attacking

Actual Behavior

1. Pressing LShift after taking damage on the broom while in the Nether prevents one from dismounting indefinitely.
2. Enderman completely ignores you while on a broom

Steps to Reproduce

1. Get hit by anything at all (even one point of suffocation damage) while riding a broom in the Nether. Only way to get off is to log out/disconnect from the game and log back in. Broom will be next to you on the ground, available for pickup
2. Get on a broom and aim the reticle directly at an Enderman

Screenshots encouraged

Logically cannot get a picture of a person trying to hit LShift to no effect, but I can post a pic of an Enderman being completely oblivious to direct "eye contact"

Logs, in the event of a crash

No crashing, just bugs.

Update: The bug that prevents one from dismounting after taking damage also applies to the overworld, I just hadn't had it happen until now.

Brooms are known for bugs. However, see #589.
